Kingdom Protista



A. Characteristics
1. Eukaryotic
2. Both Unicellular and Multicellular
3. Both Microscopic and Macroscopic
4. Autotrophic or Heterotrophic (Ingestion, or Absorption)


B. Three Groups
1. Protazoa- Animal like protists (Ingestion heterotrophs)
2. Algae- Plant-like (Photosynthetic autotrophs)
3. Psuedo Fungi- Heterotrophic (Absorption)


C. Protozoans
-Marine, fresh water and moist
-Unicellular, heterotrophs, usually Asexual
1. Amoeba- No cell wall 
	
		a.  Psuedopodia- extensions of the plasma membrane filled either, cytoplasm, freshh water, or salt water
				      - Diffusion- centralized vacoule


2. Flagellates

-Phylum Zoamastigina
-One or more Flagella
-Termite gut symbiont
-African sleeping sickness (tse-tse fly)

3. Cilliates- Phylum Ciliophora (Includes Paramecuims)
-Aquatic habitats, Asexuall, and have a form of conjugation
-Cilia, oralgroove, gullet, anal pore
-Micronucleus and Macronucleus
-Contractile Vacoule


4. Sporozoans- Phylum Sporozoa
- produce a spore reproductive cell which develops into a mature organism
- All parasites
	
		1.  Malaria- Plasmoduim



D. Algae
-Photosynthetic autotrophs
-Many different pigments
-Phytoplankton- photosynthetic plankton

1. Euglenoids
-Phylum Euglenophyta
-Unicellular
-Protien pelliele (covering)
-Autotrophic or heterotrophic
-1 flagella eyespot

2. Diatoms
-Phylum Bacillariophyta
-Golden algae
-Unicellular
-Photosynthetic
-Shells silica
-Chlorophyl and Carotenoids (orange-yellow)


3. Dinoflagellates
-Phylum Dinoflagellata
-2 flagella
-Cell walls made of cellulose
-Chlorophyl and caretenoids give it a red pigment
-Red Tide is caused by this algae


4. Red Algae
-Phylum Rhodophyta
-Red pigments
-Multicellular "seaweed"


5. Brown Algae
-Phylum Phaeophyta
-Fucaranthia pigment
-Kelp 60m long


6. Green Algae- 7,000 species
-Phylum Chlorophyta
-Unicellular, multicellular, or colonial
-Food products
-Sexual and Asexual -Gave rise to the first land dwelling plants


E. Fungus like protists
-Plasmodial slime
-Molds and cellular slime molds
-Watermolds (downy mildew)
-Potato blight of 1840
